Abstract: 384,762. Crank chambers. VILLIERS, C. A., 40, Sackville Street, London, SIMMONS, E. F., 51, Kenton Lane, Kenton, Middlesex, and MAYES, H. R., 37, Chepstow Villas, Notting Hill, London. Nov. 5, 1931, Nos. 30698/31 and 11224/32. [Class 7 (ii).] An engine having two parallel crank shafts with co-axial cylinders on each crank-throw to form an H-type engine is formed of two sections 1, 2 each composed of a crank-case part 2a and cylinder blocks 3 integral therewith. These two sections are held together by throughbolts 5 and bolts 8 connecting the pairs of cylinders together ; registration of the section is assured by spigots and sockets or by tubes or dowels 7 fitting in recesses in flanges 4 formed transversely of the sections and by keys 10 placed at the meeting surfaces of the cylinders. The end extensions 16, 17 to the case also assist in the correct assemblage of the two sections. The outer side of the walls of the crank-case have inspection openings which are closed by a common cover-plate 18 ; this is extended at one end and provided with holes 19 to receive tubes or stays right through the casing for mounting the engine on aircraft ; bosses 19a on the other end of the casing are similarly perforated. The plates 18 are sup; ported at their extended ends by bosses 20a. The inspection openings and the spaces between the flanges 4 on the inner sides of the sections facilitate assemblage of the engine.

Abstract: 766,285. Cold separation of gas mixtures. AIR PRODUCTS, Inc. Oct. 27, 1954 [Oct. 28, 1953], No. 30990/54. Class 8(2) Cooling of a compressed gas mixture e.g., air and removal of high boiling point impurities such as carbon dioxide prior to rectification in a conventional column (not shown) is effected by passage through a path 12, 16, 22 of a heat interchanger 10 cooled by partly warmed returning oxygen and nitrogen in passages 46, 56 so as to condense water vapour which is, collected in a trap 14, expansion at a valve 24 and passage through one or other of carbon dioxide precipitating chambers 25, 25<SP>1</SP> according to the setting of switching valves 27, 27<SP>1</SP>, 31, 31<SP>1</SP>; the chamber 25 in stream being traversed by cold returning oxygen and nitrogen in passages 43, 53 and the chamber 25<SP>1</SP> being derimed being traversed by nitrogen from the warm end of passage 56 flowing through the valved duct 28<SP>1</SP> previously traversed by compressed air. The interchanger 10 is assisted by a refrigerator 18 and the carbon dioxide free air is further cooled by expansion through a valve 32 to produce a mixture containing about 70 per cent liquid, which is reduced to the desired value by vaporization in ducts 36 or 36<SP>1</SP> of the chamber in stream before being delivered through a duct 38 to the column. In a modification the carbon dioxide free air instead of being cooled by expansion is led through a heat exchanger 94 Fig. 2 (not shown) traversed by cold returning oxygen and nitrogen.

Abstract: 1474099 Curing concrete RINTER TECHNIK AG 15 July 1974 31170/74 Heading B5A Concrete wall or roof panels are transported around a two-level circuit on hooded pallets while the hoods are heated for curing the concrete. A wheeled pallet 3 on the right hand end of a tunnel roof 5 receives reinforcements, inserts and mould shuttering, whereafter concrete is cast and vibrated. A sealed hood 11 is placed over the pallet by an overhead hoist 17, and the pallet moved to the left on rails 6 while the hood 11 is heated electrically by current picked up from collectors running parallel with the rails 6. At the left hand end of the tunnel roof 5, the hood 11 and shuttering is removed by a hoist 16, the concrete panel cleared and made good, and the hood 11 replaced. The pallet 3 is pushed on to a platform 18, lowered by rams 20, and pushed in to the tunnel 2 by a trolley 19. The hood is again heated by current from a collector inside the tunnel wall as the pallet is pushed through the tunnel 2 by following pallets. At the right hand end of the tunnel, the pallet is pushed on to a narrower platform 22, the hood 11 removed by hoist 17, and the pallet pivoted by a ram 28 about a radiused pallet end 30 to place the concrete panel on end on a carriage 26. The pallet is pivoted to the horizontal again, raised by rams 20 to the level of the tunnel roof 5, and repeats the cycle.

Title: Improvements relating to fluid pressure indicators

Filed: 1925-12-16
Abstract: 269,613. Bramson, M. L. Dec. 16, 1925. Elastic-diaphragm pressure gauge. - Comprises a particular construction of gauge of the two-stage diaphragm type. The cylindrical casing 1 has extending upward from the base a bracket 5 the lower portion of which carries the double diaphragm device 6, 7. The pressure fluid is conveyed to the space between the diaphragms by way of a tubular pillar 8, coiled pipe 9 and junction piece 10. Three equidistantly spaced set screws 11, 12, 13 are carried by the frame 5 so as to act as abutments to the diaphragms at their united peripheries when the latter rise to a certain extent. The movement of the top diaphragm is transmitted to a toothed quadrant 17 by means of a sharp ended strut 14 between the diaphragm and an adjustable member in a boss 15 on the spindle 16 of the quadrant. The latter engages a pinion 18 on the pointer spindle 4. A plate having knife edges engaging V-grooves may take the place of the strut. The line of thrust of the strut passes close to the axis of the quadrant giving considerable magnification. A coil spring 21 maintains a compression on the strut and a similar spring may be placed on the axle 16 of the quadrant. A weight is fitted to balance the unsupported weight of the diaphragm. The action of the pressure fluid at first is to cause both diaphragms to rise, the weaker diaphragm 7 which is anchored to the pillar 8 yielding. The united peripheries rise together until contact is made with the set screw when the change over takes place to single diaphragm action. A rigid plate may be employed adjacent the weaker diaphragm to prevent undue distortion at high pressures.

Abstract: 936,814. Centralized dictation systems. WOLFGANG ASSMANN G.m.b.H. Sept. 15, 1960 [Sept. 21, 1959], No. 31834/60. Drawings to Specification. Class 40 (4). Apparatus for the remote control of dictation apparatus over telephone lines comprises a transmitter at a calling station for transmitting signals at a pilot frequency and at a number of control frequencies, a receiver at a receiving station connected through telephone lines to the calling station, dictation apparatus controlled by the receiver, means at the receiving station for transmitting signals at a reply frequency, and a switching device at the calling station responsive to the reply frequency for controlling the connection of the transmitter to the telephone lines. The switching device contains a tuned circuit, incorporating either valves or a transistor, and a relay which is operated on receipt of a reply signal at the reply frequency after the receiving station has been called from the calling station. Operation of the relay connects the transmitter to the telephone speech wires, but the connection is maintained only if the transmitter is generating signals at the pilot frequency. The receiver is so arranged that no control operation can be performed on the dictation apparatus unless both the relevant control frequency and the pilot frequency are received simultaneously, thereby preventing accidental operation by speech, all the frequencies used being within the audible range.

Abstract: 719,179. Detecting foreign bodies electrically. AKTIEBOLAGETTELEVAKT. Dec. 16, 1952, [Dec. 18, 1951.] No. 31893/52. Class 37. Apparatus for indicating a change in the condition at a location comprises two similar oscillator circuits tuned to a common frequency, and supplied with antennae so that a change in condition as produced e.g. by the presence of a body, loads one antenna to produce a difference in frequency between the two oscillators, which difference is detected and energizes an alarm circuit. As shown, two triodes 1, 2 with common cathode resistor, 17, have similar tuning circuits 3, 4 tuned to the same frequency, inductively coupled in opposition to a triode 6. Normally the beat frequency is zero, but with the presence of a body near one of the antennae A 1 , A 2  a beat frequency is produced which, after rectification at 6, is amplified to supply negative bias to a triode 9 thereby cutting its anode current to allow a relay Ri to energize and close an alarm circuit A via contacts 12. The circuit is reset by manually operated contacts 14 in parallel with normally closed contacts 13 of relay R 1 . The alarm beat frequency may be aurally detected by phones T in the anode circuit of triode 6. Failure of the supply voltage de-energizes a relay R 2  to break the alarm circuit A at contacts 15, and close a warning circuit F over contacts 16.
